Seminář CFRJS

Centrum fyziky ultra-relativistických jaderných srážek (CFRJS) zve na odborný seminář dr. Petra Jizby s názvem "A new class of entropy-power-based uncertainty relatios" [PDF] , který se uskuteční v pátek 13. 11. 2015 v 9:45 v místnosti B115.

Abstrakt přednášky:

In my talk I will use the concept of entropy power to derive a new one-parameter class of information-theoretic uncertainty relations for pairs of conjugate observables in an infinite-dimensional Hilbert space. This class constitutes an infinite tower of higher-order cumulant uncertainty relations, which allows one in principle to determine shape of the underlying distribution in process akin to quantum tomography. I will illustrate the potency of the new class by studying two particular examples: superpositions of vacuum and squeezed states and the Cauchy-type heavy-tailed wave function.
